This tutorial details all the steps needed to determine the EC8 class of a site from the input of the velocity profile

The input is the soil column (in a format similar to gpsh geopsy:gpsh The output is the EC8 site class depending on the value of time-averaged velocity over the top 30 m ("VS30")

gpec8 -help Usage: gpec8 [OPTIONS] [FILE] Print EC8 site class corresponding to intput models

Format for layered models:

 Line 1  : <number of layers n including half-space for first model>
 Line 2  : <thickness (m)> <Vp (m/s)> <Vs (m/s)> <Density (kg/m3)>[ <Qp> <Qs>]
 ....
 Line n+1 : 0 <Vp (m/s)> <Vs (m/s)> <Density (kg/m3)>[ <Qp> <Qs>]
 Line n+2 : <number of layers m including half-space for a second model - if wished>
 Line n+3 : <thickness (m)> <Vp (m/s)> <Vs (m/s)> <Density (kg/m3)>[ <Qp> <Qs>]
 ....
 Line n+m+2 : 0 <Vp (m/s)> <Vs (m/s)> <Density (kg/m3)>[ <Qp> <Qs>]
 Line n+m+3 : <number of layers l including half-space for a third model - if wished>
 ....

Quality factors are not mandatory. Any number of models can be given as input.
